XmlSerializer序列化时是不是不能加注释

public class Rule
{

public string device;
public int channel;
}
//序列化List
private void Serialize(List list)
{
XmlDocument xd = new XmlDocument();
using (StringWriter sw = new StringWriter())
{
try
{
XmlSerializer xz = new XmlSerializer(list.GetType());
xz.Serialize(sw, list);

xd.LoadXml(sw.ToString());

xd.Save("a.xml");
}
catch (Exception ex)
{
MessageBox.Show("序列化时发生错误：" + ex.Message);
}

        }
    }
            如果不使用XmlDocument去修改XML,那怎么才能让XmlSerializer生成的xml中包含对device和channel节点的注释？
            先谢谢各位了。
